摘要
针对煤矿火灾、水灾、瓦斯突出、瓦斯爆炸等事故在煤矿生产中频发的问题,设计了一种通过远程或就地控制实现关闭的井下快速密闭装置。该装置能够有效减小煤矿灾害的规模。快速密闭门是井下快速密闭装置的重要结构之一,通过理论计算,确定了快速密闭门所受到的冲击载荷,并基于ANSYS/LS-DYNA对门体结构进行了有限元分析。结果表明:门体结构可抵抗不低于0.6 MPa的瓦斯爆炸冲击。
In view of the frequent occurrence of coal mine fire, flood, gas outburst, gas explosion and other accidents in coal mine production, a kind of underground fast sealing device was designed to close through remote or local control. The device can effectively reduce the scale of coal mine disasters. Fast airtight door is one of the important structures of underground fast sealing device. Through theoretical calculation, the impact load of fast airtight door was determined, and the structure of the door was analyzed by finite element method based on ANSYS/LS -DYNA. The results show that the door structure can resist gas explosion impact not less than 0.6 MPa.
